Description

This function will calculate the negative log likelihood value when the vector of binomial random variables and vector of corresponding frequencies are given with the input parameters.

Usage

1
NegLLCorrBin(x,freq,p,cov)

Arguments

x

vector of binomial random variables

freq

vector of frequencies

p

single value for probability of success

cov

single value for covariance

Details

freq ≥ 0

x = 0,1,2,..

0 < p < 1

-∞ < cov < +∞

NOTE : If input parameters are not in given domain conditions necessary error messages will be provided to go further

Value

The output of NegLLCorrBin will produce a single numeric value
